Hipo service block ID

sdully88_old · November 30, 2009 at 8:00 PM

Can someone please give me some tips on how to ID a hipo service block? I know there won't be a VIN #, but what else separates it from a standard hipo block? I think I may have one but want to be sure. Definitely has the hipo main caps. Thanks

Start by checking the casting date code and the assembly date (if there is one) stamped on the front boss behind the timing case cover...If these dates are 1967, you're possibly dealing with a replacement block, and if the date is later than 1967, then it's a replacement.

My NOS Service Replacement Block was discussed on this forum at the link below. It had no evidence of orange paint as you would have in a factory installed HIPO. However it did have a faint white HP lettering on the back of the block.

I have an H65 dated hipo engine in my Kar that does not have a VIN stamp and is date stamped 5J17P. I have been told that this is a sevice engine, but I have always thought it was way too early to be one. When I found this engine, it was in a pickup truck. It had all the shelby engine parts including a correct dated 3259 carb on it.
